Authorities on Sunday identified the Fillmore man killed in a head-on crash Friday night north of Moorpark.

The driver of one of the vehicles was Moises Paniagua, 58, according to the Ventura County Medical Examiner's Office.

Four other people were injured in the two-vehicle collision on Highway 23, according to the California Highway Patrol.

The accident was reported around 10:35 p.m. in wet conditions on a curve where the state route turns roughly 90 degrees.

Paniagua was driving a green Honda Accord sedan northbound on a segment of the highway known as Walnut Canyon Road that extends north of Moorpark city limits. The Honda was approaching the left curve in the roadway. Three female passengers were in the Honda, all Fillmore residents with the same last name as the driver, according to the CHP. They were 51, 22 and 16 years old.

On the other side of the curve, where the highway runs east-west for a stretch and is called Broadway Road, a 46-year-old Moorpark woman was driving a black Ford F-350 pickup truck eastbound. No one else was in the truck.

Parts of Ventura County had experienced intermittently heavy rain and thunderstorms that night, the CHP reported, and roads were wet. CHP officials believe it may have been raining at the time of the crash.

The two vehicles collided head-on, or nearly head-on, in the curve, the CHP reported. Paniagua was badly injured and trapped in the car, authorities said. He was extricated by Ventura County firefighters. The 51-year-old female passenger suffered major injuries, and the younger female passengers suffered moderate injuries, authorities said.

All four were taken to Los Robles Regional Medical Center in Thousand Oaks. Paniagua died overnight despite aggressive medical care at the hospital, the CHP reported.

The driver of the pickup truck suffered minor injuries, including seat belt and airbag abrasions, and was treated at the scene, authorities said.

All five people had been wearing seat belts, the CHP said. Authorities said alcohol and drugs did not appear to be a factor in the collision.

Anyone who saw the crash is asked to call the CHP's Moorpark office at 805-553-0800.
